Hi Scott,
The errors are related to Jersey not being able to find some classes
whose names are declared in a META-INF/services file (present in the
jeresy-core jar).
This could be because of re-package issues. Have you re-packaged
Jersey classes?
Or it could be related to class loading issues. How are you running
the client?
Jersey attempts to load the classes using the thread context class
loader [*]. One thing you can try is to set the thread context class
loader before you create the Client.
Paul.
[*] i think i need to change loading to fall back to the defining
class loader of the currently class if look up fails, but i do not
know if that will solve your problem.
